If you installed the English version, you can patch up to v1.79.

But you may have to apply a relatively recent UK English patch first. Whomever it was doing this last could not get the US English patcher to recognize the install until the last UK English patch was applied.

I believe the issue was patching the Euro v1.30 with a Euro v1.33 patch, which no US SE5 patch worked with. However, going from the v1.30 patch to v1.79 was possible.

The last person that was posting about this on se5.com could not get the US patch to apply to a freshly installed UK English version, and had to apply a patch first.
